Patent DE-2848993-A1 (DE)
Inventor: FITZKY HANS GEORG DIPL PHYS DR
IPC: H01P7/06
Filed: 1978-11-11
Abstract: The generator for the microwave measuring arrangement consists of a frequency-modulated oscillator which feeds a cavity measuring resonator in a transmission arrangement. The sample to be examined is located in the center of the resonator. The microwave signal allowed through the resonator is detected as the peak amplitude of a detector circuit, the change in the signal corresponding to the change in the quality factor due to the presence of the sample introduced. The average frequency of the microwave oscillator can be switched over several stages in order to expand the range of measurement. Each time the frequency is switched over, a different field mode is excited in the measuring resonator so that the sample is located in a mode region of the electrical measuring field for measuring high water contents and in a maximum of the electrical measuring field for measuring low water contents.

Patent DE-2855790-A1 (DE)
Inventor: KOSKI JOHN ALEXANDER
IPC: G11B15/44
Filed: 1978-12-22
Abstract: Apparatus and method for controlling a reel-to-reel tape drive so that its performance characteristics are optimized to best suit the operational mode or availability of a host system by modifying tape speed adaptively according to predetermined conditions sensed during processing of data (i.e., while the tape is in motion). For example, tape might initially be fed at a high speed suitable for archiving; but if more than a predetermined number of "backhitches" (overruns of the interblock gap, IBG) occur during processing of a preselected number of successive blocks of data, the host will cause tape speed automatically to be reduced to a lower rate. This lower rate will enable the tape to stop in the IBG and is therefore suitable for intermittent processing. Preferably, before reducing speed during write operations, appropriate signals are generated at the host to command an increase in the IBG from a normal distance to a larger distance if backhitches exceed said preselected number. If this fails to reduce backhitches to an acceptable level, speed will be reduced to the lower rate and the gap preferably restored to its normal distance.

Title: Servo-hydraulic control for hydraulic motor - has control and regulating pistons which centre to control hydraulic pressure
Inventor: KUCHARZYK REINHARD
IPC: F15B13/043
Filed: 1979-02-12
Abstract: The servo hydraulic device is for the load-independent control of the hydraulic action of a double acting hydraulic motor of an engine with a multiple control slide which allows fluid flow to the motor. The size of the hydraulic flow from two annular chambers at 4 bar difference pressure is dependent on the opening cross-section of the movable choke head on the main control and main regulation pistons. These centre on the main control piston by centring springs and sprung thrust bearings until 4 bar hydraulic pressure is held in this centring position. It leaves this position when the pressure exceeds 4 bar so that the opening cross-section between the annular chambers vary to maintain the hydraulic pressure difference.

Title: Induction tunnel oven for metal workpieces - has power to induction coil applied in pulses until workpiece core reaches wanted temp.
IPC: H05B6/06
Filed: 1979-04-09
Abstract: The induction oven has its supply of power repeatedly interrupted whilst the workpiece is being heated up to the wanted temp. This interruption takes place depending on the temp. difference between the workpiece surface and its core and continues until the core reaches the wanted temp. as long as a difference exists between the temp. at the surface and at the core. During this latter stage the workpiece surface temp. is kept within a given range. The power to the induction coil is switched by two anti-parallel thyristors in series with the coil via a ballast resistor (that may be shunted out). The thyristors are triggered according to the workpiece temp.

Title: Multistage wide band HF amplifier - is constructed on both sides of circuit board with earth conductor acting as screen between stages
Inventor: GEORGE FRANCISCO
IPC: H05K1/02
Filed: 1979-04-23
Abstract: The mechanical construction of the circuit reduces interference between stages of the amplifier whilst being compact. The successive amplifier stages are placed on opposite sides of a printed circuit board. The earth, or reference voltage, conductor is extended to act as a h.f. screen between stages. The etching on the board is therefore kept to a min. in order to maintain the effectiveness of the screening. In a typical construction the output section of an amplifier stage is exactly opposite the corresp. input stage. Screening between the adjacent stages on the same side of the board can be provided by barriers forming part of the case enclosing the whole circuit. These barriers make contact with the screen conductors on the circuit board to give full isolation between stages.

Abstract: In the case of a discharge lamp (L), which may be a lamp for an AC voltage of 220 volts, for example, in order to obtain rapid, flicker-free starting, the said lamp is briefly connected, during switching on, to a starting voltage which is higher than the supply voltage. The starting voltage is produced by a high-reactance autotransformer (W). Apart from the iron core (EK), this transformer also comprises two coils S and R. A switch (IS) comprises a pulse switch which has clamping springs (F) and contact pieces (KP). When the switch (IS) is operated, that is to say during the process of switching the lamp (L) on, the starter coil (R) is briefly driven by the pulse switch, as a result of which the starting voltage is produced. The latter is produced by the current-limiting coil (S) and is applied to the electrodes (E1, E2) of the discharge vessel (T1, T2) of the lamp (L). After the starting process, the normal operating voltage is applied to the electrodes (E1, E2) via a contact blade (M) of a wiper contact of the switch (IS). The electrodes (E1, E2) are pre-activated. <IMAGE>
